Product details
Overview
SBR8M100P5Q-13 from Diodes Incorporated is an AEC-Q101-qualified Super Barrier Rectifier (SBR) in PowerDI5 package, rated for 100 V reverse voltage, 8 A average forward current, and 0.88 V max forward voltage at 8 A/25°C. It delivers soft, fast switching with 16 ns reverse recovery time and supports automotive polarity protection, DC-DC converter freewheeling, and ISO7637-2 surge immunity up to ±600 V.
For engineers reviewing the SBR8M100P5Q-13 datasheet, SBR8M100P5Q-13 pinout, SBR8M100P5Q-13 application, or SBR8M100P5Q-13 equivalent, key selection criteria include its low VF at high temperature, 130 A non-repetitive surge rating, 400 mJ avalanche energy (5A/50mH), RoHS- and halogen-free "Green" construction, and IATF 16949-certified manufacturing.
Technical Context
This SBR diode replaces conventional Schottky and standard PN rectifiers in automotive power rails where low conduction loss and robust transient survivability are required. Its patented Super Barrier Rectifier technology enables lower forward voltage than comparable Schottkys while maintaining superior thermal stability and reduced leakage at 125°C and 175°C junction temperatures.
The device operates across -55°C to +175°C, features 4000 V HBM ESD rating, and achieves 245 pF junction capacitance at 4 V reverse bias. Its thermal resistance is 25°C/W on 2-inch² Al board and 90°C/W on FR-4 - critical for thermally constrained under-hood layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Blocks up to 100 V DC or peak AC reverse voltage without breakdown. |
| IO (AVG) | 8 A - Sustains continuous forward current up to 8 A at TA = 25°C with derating above 25°C. |
| VF (MAX) | 0.88 V @ 8 A, 25°C - Minimizes conduction loss in high-current paths like 12V/24V DC-DC outputs. |
| tRR | 16 ns - Enables efficient high-frequency switching (>100 kHz) with low switching loss and EMI. |
| IR (MAX) | 100 µA @ 100 V, 125°C - Ensures low standby leakage in battery-sensitive systems like always-on ECUs. |
| EAS | 400 mJ @ 5A, 50mH - Withstands single-pulse inductive energy surges common in solenoid/relay drive circuits. |
| RθJA | 25°C/W (Al board) - Supports >5 W dissipation at ΔT = 125°C, enabling compact heatsinkless layout in space-constrained modules. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed heat sink pad on bottom side; dimensions 3.966 mm × 6.51 mm × 1.10 mm; UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Forward current entry terminal | Connected to input/high-side rail; must be electrically tied to right pin (cathode) on PCB for thermal path to copper pour. |
| Cathode (Right Pin) | Forward current exit terminal | Connected to output/load ground; forms low-inductance return path when paired with left pin on shared thermal pad. |
| Bottom Heat Sink Pad | Thermal and electrical reference plane | Internally connected to cathode; requires soldered copper area ≥ 200 mm² for optimal RθJA and surge current handling. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Combines Schottky-like VF with PN-diode-level thermal stability and leakage control up to 175°C. |
| Soft, Fast Switching | 16 ns tRR with minimal reverse recovery tail current - reduces voltage overshoot and snubber losses in flyback/freewheeling stages. |
| AEC-Q101 Qualified | Validated for automotive use including HTOL, TC, UHAST, and ESD testing - supports PPAP documentation and change control traceability. |
| "Green" Construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); RoHS 3 compliant; matte tin annealed terminals for reliable solder wetting. |
Applications
| Automotive Polarity Protection | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Reverse-battery connection protection in 12V/24V vehicle infotainment head units and body control modules. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between battery input and downstream regulator ICs. Use Value: Withstands ISO7637-2 Pulse 1 (-600 V) without failure; 0.74 V VF at 8 A/125°C ensures minimal voltage drop during cold-cranking. |
Use Scenario: Output rectification in synchronous buck converters powering ADAS camera modules and radar processors. IC Role / Device Role / Timing Role: Freewheeling diode providing current path during high-side MOSFET off-time. Use Value: 16 ns tRR minimizes cross-conduction loss; 400 mJ EAS absorbs inductive kickback from 50 µH chokes at 5 A. |
| Engine Control Unit (ECU) Power Rail | Start-Stop System Battery Management |
Use Scenario: Input protection and hold-up rectification in engine ECU power supplies subjected to load-dump transients. IC Role / Device Role / Timing Role: Blocking diode isolating main 12V rail from auxiliary 5V/3.3V LDOs during transients. Use Value: 130 A IFSM handles 8.3 ms load-dump surges; 175°C TJ rating maintains reliability in under-hood ambient up to 125°C. |
Use Scenario: Bidirectional isolation in 12V start-stop battery management circuits with regenerative braking energy recirculation. IC Role / Device Role / Timing Role: Re-circulating diode enabling controlled discharge of stored energy into starter motor or auxiliary loads. Use Value: Low VF (0.65 V @ 4 A/125°C) reduces power loss during frequent charge/discharge cycles; soft recovery prevents gate driver interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT8M100P5-13 | Same PowerDI5 package, identical VRRM/IO, but uses standard SBR (not "M" grade); VF slightly higher (0.92 V max @ 8 A). | Lacks AEC-Q101 qualification and PPAP capability; not approved for safety-critical automotive functions. | Select only for cost-sensitive non-automotive industrial power supplies where qualification is not required. |
| MBR8100FCT-TP | TO-220AC package, same 100 V/8 A rating, but Schottky-based; VF = 0.85 V max @ 8 A, yet IR = 1000 µA @ 125°C - 10× higher leakage. | Higher thermal resistance (30°C/W typical); unsuitable for sealed enclosures or high-ambient environments. | Prefer only where through-hole mounting is mandated and leakage tolerance exceeds 100 µA at 125°C. |
Compared with SBRT8M100P5-13 and MBR8100FCT-TP, SBR8M100P5Q-13 uniquely combines AEC-Q101 compliance, ultra-low high-temp leakage, and optimized thermal performance in a surface-mount PowerDI5 footprint - making it the only qualified choice for automotive-grade DC-DC and ECU protection where reliability and space constraints coexist.

FAQ
What is the maximum junction temperature rating for SBR8M100P5Q-13?
The device is rated for continuous operation from -55°C to +175°C junction temperature. This allows deployment in under-hood automotive locations where ambient temperatures exceed 125°C, provided thermal design maintains TJ ≤ 175°C using the specified RθJA values and PCB copper area.
Is SBR8M100P5Q-13 compatible with lead-free reflow profiles?
Yes - it features matte tin-annealed terminals and is qualified for standard IPC/JEDEC J-STD-020 lead-free reflow profiles, including peak temperatures up to 260°C. Moisture sensitivity level is Level 1, eliminating bake requirements prior to assembly.
How does the PowerDI5 package improve thermal performance over SMA or SMB packages?
PowerDI5 integrates an exposed cathode pad that serves as both electrical terminal and thermal interface. When soldered to ≥200 mm² of 2-oz copper, it achieves RθJA = 25°C/W - ~40% lower than SMA packages - enabling higher power density and eliminating need for external heatsinks in many automotive applications.
Does SBR8M100P5Q-13 meet ISO7637-2 Pulse 1 requirements for 24V systems?
Yes - the device withstands -600 V transient pulses per ISO7637-2 Pulse 1 (24V system) due to its 100 V VRRM rating combined with 400 mJ avalanche energy capability and robust junction design. It is explicitly validated for this use case in Diodes' automotive application guidance.
